Question

During the process of electrolytic refining, the pure metal is deposited at the ________.

• A. anode
• B. cathode
• C. bottom of the anode
• D. initially at cathode and then at anode

Answer 1

The correct option is B cathode

During electrolytic refining, on passing the current through the electrolyte, the pure metal from the anode dissolves into the electrolyte and an equivalent amount of pure metal from the electrolyte is deposited on the cathode.

The soluble impurities go into the solution, whereas, the insoluble impurities settle down at the bottom of the anode and are known as anode mud.
